PERMUTATION-LOOK FOR SAFES.

Application filed July 17, 1919.

To all whom it may concern:

Be it known that I, ELLswoRTH E. QUAINTANGE, a citizen of the United States, residing at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Permutation-Locks for Safes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of thls s aecification.

My invention relates to improvements in locks, more especially adapted for use in connection with the doors of safes and vaults, my object being to provide an effic ient and secure lock of this character, which shall at the same time be comparatively simple in construction and economical in cost.

The framework of the lock is circular in front and rear view, its outermost plate be ing the largest, the said framework being stepped inwardly toward the axis of the door from the outer to the inner plate, as is customary in vault and large safe doors.

Mounted within the inner portion of the framework is the lock mechanism proper, consisting of a cylindrical structure comprising a hollow core, upon which are mounted a number of tumblers independently adjustable, and each containing an outer adjustable body member carrying a numbered disk which is adjustable within the body of the tumbler for the purpose of changing the combination; and a second disk which, while removable, is permanently positioned in the tumbler and is provided with recesses ada ted to en a e a click ball Specification of Letters Patent.

however, are of such size as to prevent the balls from passing through. Any desired number of tumblers may be employed. The body member of each tumbler has an inwardly projecting collar, which is slotted or toothed to engage the edge of a pallet member, which is mounted in the hollow core of the tumbler mechanism and provided with parts projecting beyond the same whereby the pallet member is adjustable Vertically from the outside. Normally this pallet member is disengaged from the slots or recesses of the body of the tumbler and it works in conjunction with a second pallet member of similar construction but which is so shaped as to enter a recess or slot formed in the numbered disks, also of the tumblers when the combination of the lock is solved or when the recesses of all the numbered disks are in longitudinal alinement.

Before solving the combination, the first named pallet member may be moved a short distance, whereby it is caused to engage the aforesaid slots or recesses of the bodies of all of the tumblers, and whenso adjusted, locks the tumbler members against rotation. The construction for adjusting the two pallet members is of such character that the first pallet member is first actuated to engage the slots of the bodies of the tumblers if the combination is solved the second pallet member will, by the same operation, its movement however, being slightly later, engage the slots or recesses of the numbered disks. W hen this occurs, the second pallet member is in such position that a rod accessible from the outside may be adjusted longitudinally to permit the rotation of an operating spindle which adjusts a relatively large disk located within the framework of the door and which is so connected with locking bolts that the latter may be withdrawn from the portion of the safe surrounding the door, whereby the latter is free to open. The tumblers of the lock mechanismare rotatably adjusted from the outside through the medium of a series of spindles whose inner extremities carry pinions which engage gears formed on the bodies of the tumblers. The second pallet member has a part detachable from the inside of the safe or vault, so that the door can not be opened from the outside even when the combination of the lock is solved, thus enabling a a safe or vault provided with a door equipped with my improved lock mechanism.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the circular framework of a safe or vault door, having an outer plate 6, an inner plate 7, and an intermediate plate 8, dividing the cavity of the framework into front and rear compartments 9 and 10. The outer circular portion of the casing between the plates 6 and 7 is stopped, as shown at 12, as is customary in structures of this character. WVithin the forward compartment 9 is located a rotatable disk 13, which is journaled upon a central sleeve 1%, having an exteriorly projecting circumferential flange 15, which engages the intermediate plate 8. The disk 13 is enby a second sleeve 16, having an interiorly projecting flange 17, which engages the outer of the sleeve 14-. The lislr13 is provided with a number of curved slots l8, wh ch engaged by pins 19 connected with bolts 20, which are shiftable outwardly and inwardly by the movement of the disk are properly adjusted, a rod 27 may be moved longitudinally to the position shown in Fig. 14, after which the disk 13 may be moved for the purpose of shifting the bolts 20 to the unlocked position, all as hereinafter more fully explained.

The tumbler mechanism of the lock and the manner of operating the same, will now be described.

This mechanism is inclosed in a casing 28, inserted in an opening formed in the rear plate 7 of the door, said casing extending through the compartment 10 and abutting against the rear surface of the plate 8. This casing projects inwardly beyond the plate 7 and is closed on the inside by a removable plate 29, for convenience in removing the tumbler mechanism for the purpose of changing the combination, or when for any reason such removal may be necessary. This casing 28 must be rigidly secured in place upon the door, and this may be accomplished in any suitable manner. WVithin the casing 28 the tumbler mechanism may be inserted in its entirety when the pallet members are 7 in position, inasmuch as the top and bottom walls of the casing 28 are slotted to receive the vertically projecting parts of the pallet members, as hereinafter more fully described.

The tumbler mechanism consists of a central core 30 (see Fig. 10), which is provided with a long longitudinally disposed slot 4 at the top, and a relatively narrow slot 31 at the bottom, the last named slot being provided to accommodate the lower vertical projections 32 and 33 of the respective pallet members 25 and 26. ithin this core, which is hollow, are located the parts 34 or the pallet member 25, which extend at right angles in opposite directions from the vertical parts; and the similar parts 35, which extend in opposite directions from the vertical parts of the member 26. The parts 34 of the pallet member 25 are provided with four upupwardly projecting parts 36, which are adapted to respectively enter recesses 37, formed in the inwardly projecting flanges 38 of the four tumblers 39. The lower part 32 of the pallet member 25 passes through the slot 31 of the core, and also through an opening 41 in the bottom of the casing, while its upper vertical part 40 passes through the slot 4 of the core and an opening 42 in the top ot' the casing. These openings 41 and 42 of the casing extend rearwardly through the respective parts or" the casing and are open until the rear plate 29 is put in place, thus making it practicable to introduce the entire tumbler mechanism with the pallets in place into the casing 28 when the rear plate is removed, as heretofore explained.

The parts 35 of the pallet 26 are cut away in four places, as shown at 43, to make room for the parts 36 of the pallet 25, so that the two pallets may be in actual contact but independently movable, the parts 36 being laterally offset from the parts 34 of the pallet 25, as best illustrated'in Fig. 23. Furthermore, the parts 35 of the pallet 26 are provided with parts 44, which are adapted to enter recesses 45 "formed in the several numbered disks 46 of the several tumblers. These parts 44 are so located and arranged that they can only engage the slots 45 of the disks 46 when these disks are all so positioned that the recesses 45 are in longitudinal alinement; and when this is the case the combination is solved.

Each disk 46 is numbered from 0 to 20, whereby it may be given twenty-one different positions in its tumbler member, and every change of position changes the combination of the lock.

There is a series of recesses 47 in the outer edge of each disk 46, the various recesses 47 being positioned to correspond with the respective characters of the disk. The cupshaped body member 39 of each tumbler contains a slight inward projection or tongue 48, adapted to enter any recess 47 of the disk 46. Hence, in inserting the disk 46 in the cup-shaped member 39, it may be so positioned that any one of its characters, from 0 to 20, will be opposite the tongue 48 of the body member of the tumbler and the necessary adjustment in order to solve the combination will depend upon the positions of the various disks 46 in their respective tumbler members 39. The recesses 45 of the disks 46 are always in alinement with one of the recesses 37 of the body member of the tumbler, and with a recess 49 of a disk 49, which is inserted in the tumbler member after the disk 46 is put in place.

The positioning of the disks 46 and 49 in each tumbler member may be readily understood by reference to Fig. 27.

As shown in the drawing, the disk 46 is spaced from the slotted flange 38 of the tumbler member 39 by a ring 50. This, however, is not particularly important and may be employed or not, as desired.

Assuming that the spacing ring 50 and the two disks 46 and 49 are inserted in each tumbler member and that there are four tumblers in the lock mechanism, as illustrated in the drawing. and that these members are aranged on opposite sides oi the central portion of the tumbler mechanism, and that the open extremities of each pair of tumbler members 39 are turned toward each other, as well illustrated in Fig. 27, a spacing member 51 is mounted on the core and projects into the open ends of the two tumbler members outside of the core. Each of these spacing members 51 is provided with two projections 52 between which is located a sleeve 53, in which is arranged a spiral spring 54, which acts at its opposite extremities on balls 55, which extend partially through openings 56, formed in the projections 52. The spring 54 is under compression between the two balls and normally forces said balls outwardly to their limit of movement. 'hese balls are positioned to engage the recesses ll) of the two disks 49 of the corresponding pair of tumblers. Hence, as any tumbler is rotated, the number of spaces is determined, either audibly or through the sense of feeling, since every movement of a tumbler member rotatably upon the core for a distance canal to that between two or the recesses 49 oi a disk 4E9, will cause the adjacent ball 55 to be pressed inwardly against its spring until the recess is reached, when the ball will move outwardly'into saidv recess a short distance, procucing either a click, or at least a slight jar, which is noticeable by the operator through the sense of feeling.

T he spacing member 51, arranged between each pair of tumblers, so fiXGLl upon the core that a slot 57', formed therein, registers with the slot l of the core, this slot 57 making it practicable for the parts i l of the pallet member 26 to move upwardly into engagement with the several l5 of the numbered disks and the registering recesses 49 of the disks 49, when the combination is solved.

Applied to the central portion of the core 30 are two abutting sleeves 58, which have inwardly extending flanges 59, which respectively engage the adjacent flanges or" the adjacent tumbler members 390 These sleeves are slotted at the top and bottom, as shown at 60 and 61, to receive the upper and lower vertical parts of the two pallet members so and 26. These slots 60 and 61 register with the slots 1 and 31 of the core 30, and with the openings ll and 4-2 of the casing. The tumbler members are securely clamped. upon the core through the medium oi two heads 62 and 63, which are centrally chambered as shown at 6% to receive the opposite ends of the core, the portions of the heads around the central cavities abutting against the adjacent tumbler members 39, these heads being adjustable by means of set screws 65, threaded into the opposite ends of the easing 28 and centrally engaging the respective heads. By adjusting these screws, the turnblers are properly adjusted lengthwise oi? the core, so that while they may be turned freely thereon. they will not be too loose.

Each tumbler is provided with a relatively large cxteriorly projecting bevel gear 66, the several gears 66 respectively meshing with pinions 6?, fast on the inner er:- tremities of spindles 68, whose outer extremities are provided with knobs ($9, for convenience of adjustment. By virtue oi this construction, a person who knows the combination may readily adjust the tumblers to solve the combination by the manipulation of the knobs 69. The upper vertical part 40 of the pallet member 25 is provided with an opening 70, vertically elongated, while above andbelow said opening are flanges 71 and 72, adapted to engage a cam 73, mounted on a spindle M, the cam being otthe eccentric type and so arranged that when in a predetermined position of rotary adjustment it will lift the pallet 25 and cause the pro jcctions 86 to engage the recesses 37 of the various tumbler members 89. The spindle 1 i is journaled in the plates 6, 7 and 8, of the door and extends entirely therethrough, its outer. extremity having knob 75 to facilitate manipulation. This spindle may be turned at any time, even when the mechanism is in the locked position, sniiiciently to lift the projections of the pallet 25 into ene'ao'ei'nent with the recesses 37 of the respective tumbler me: bers 3 and when this is done, the tumblers can not be rotated or acjusted for the purpose of solving the comiation. This provision is important from he fact that it confuses an evilly disposed person'who is endeavoring to open the lock and at the same'time it is a safety provision, i r, when the pallet is lifted, to cause the projections 36 to engage the tumbler meiobers aforesaid, the tumblers can not be moved all. Furthermore, the upper extremity or the vertical part 83 of the pallet member 26 is provided with a similar vertically elongated opening; 76, which registers with the similar opening 'ZO of the pallet member 25. There are also upper and lower flanges 77 and 78, formed on the part 33 at the opposite end of the opening; 76. There is a cam 79 also mounted on the spindle 74 and adjacent the cam 73. lhese cams, however, while of the same shape. are differently positioned, as indicated in Fig. 19, in which figure the mechanism is shown with the pallets adjusted to aermit the unlocking of the door. lhe two pellets are so positioned in relation to each other that the two flanges 71 and 1 2 of the one pallet member project in opposite directions from the corresponding: flanges 77 and 78 oi the other pallet member, as illustrated in Figs. 5, 6 and '7. The two cams are sli htly spaced, and. the portion. of the spindle betewen the cams passes through the two registering openings and 76. The function of lower portion 32 of the pallet member 25 is to accurately guide the pallet and maintain it in its proper relative position at all times, as this part passes through the slot 31 of the core 30, slot 61 of the sleeves 58 and slot 41 or the casing. However, the lower vertical part 33 of the pallet member 26 has a part 89 detachably connected therewith by means of a bolt 81, which passes through an opening 82, formed in the part 33, and a regis terinp opening 84 formed in the part 80. .lhis part 80 is slidably mounted on the inner plate '4' oi": the door, the part 80 having receive the edges of the plate 7 on opposite sides of a slot therein, which receives the grooved offset part 85, the part 80 being applied to the plate from above and before the casing 28 is put in place. Normally, or when the mechanism is in the locked position, the pallet member and part 8% connected therewith are in their low-e ost position, or that illustrated in Fig. 4. The part 80 has an opening 87. whose lower part is enlarged, as shown at receive the inner extremity 89 of the rod 27, which passes through the door and is pr=::=vided at its outer extremity with a knob 90. The upper part 91 of the opening 8'? in the partSll is reduced in size as compared with the part 88, but is large enough to receive a reduced part 92 of the rod 27, which is just forward of the extremity 89, this reduced part or neck 92 occupying the part 91 of the opening 8? when the mechanism is in the locked position, shown in Fig. 4;. When the com bination of the tumbler mechanism is solved, the two pallet members may be raised by imparting partial rotation to toe spindle 74, through the medium of the cams 7 3 and 79. This upward movement of the pallet member 26 lifts the part 80 and brings the part 88 of the opening 87 into horizontal alinement with the inner extremity 89 of the rod 27, and permits this rod to be moved outwardly to the position shown in Fig. 14:. since the inner extremity 89 of the rod will enter the part 88 of the opening, but is too large to enter the part 91. This outward movement of the rod 27 brings a reduced part 93 of the rod 27 into alinement with a curved slot 94, formed in the movable disk 13. One extremity 95 o this slot 94 is large enough to receive the body part of the rod 27, but the latter is too large to pass through the main portion of the slot 94; hence, when the rod 27 is at its inward limit of movement, as illustrated in Fig. 4, the disk 13, which actuates the locking bolts 20, as here tofore explained, can not be moved for locl'- ing or unlocking purposes. but as soon as the rod 27 is moved outwardly to the position shown in Fig. 14. and the reduced part 93 of the rod is brought into alinement with the slot 94. the plate may be moved rotatably for unlocking the door, since the reduced part 93 is of such size as to enter the slot 94. Hence, when the rod is moved to the position shown in Fig. 14, the disk 13 may be moved from the position shown in Fig. 8 to that shown in Fig. 18 by turning the spindle 23, in which event the pinion 22 engages the segmental gear 21 for the purpose.

It should also be explained that the plate 13 is provided with a slot 96 of sufficient width to receive the spindle 23, and of sufiicient length to permit the necessary movement for operating the bolts 20. Further:

more, the disk 13 is slotted as shown at 97 to receive the spindle 7& which operates the cams; as heretofore explained, this slot must be of sufficient length to permit the necessary movement of the disk 13.

Attention is called to the fact that the spindle 23 is also rovided at its inner extremity with a hand-held 98, whereby the disk 13 may be manipulated for looking or unlocking the door from the inside. For instance, in the event that a bank oflicial may find it necessary, in order to protect himself, and the contents of the vault, to enter the vault through the door, he may by grasping the hand-hold 98, lock the door and detach the part 80 from the palletmember 26, thus makin it impossible to manipulate this part by lifting the pallet 26. And as this part 80 can not be lifted, the rod 27 can not be moved outwardly to the position shown in Fig. 14, and consequently the disk 13 can not be operated for the purpose of unlocking thesafe from the outside. When, however, the person within the vault wishes to open the door, he may lift the part 80 into position to allow the inner extremity 89 of the rod 27 to pass through the part 88 of the opening, after which he may push the rod 27 to the operative position shown in Fig. 14. Then, by operating the spindle 23 from the inside, he may unlock the door and let himself out.

From the foregoing description, the use and operation of my improved lock mechanism will be readily understood.

If we assume that the door is locked and it is desired to open the a me, a party know the combination would at first manipulate the tumblers through the medium of the knobs 69, the spin dies 68, the pinions 67. and the gears 66, as heretofore explained. When these tumblers areproperly m. nipulated, all of the numbered .disks 4-6 will be so adjusted as to bring the recesses 4L5 into alinement with the upper edge of the parts 44 of the pallet 26. Then. by operating the spindle 74, which carries the cams 73 and 79. the two pallet members 25 and 26 will be raised and the part 80. connected with the pallet member 26, will be lifted to bring the part 88 of its opening 87 into alinement with the inner extremity 89 of the rod 27. This rod 27 may then be moved outwardly to the position shown in Fig. 14:, whereby the reduced part 93 of the rod is brought into alinement with the slot 94:, permitting the disk 13 to be given a partial rotation in the direction of arrow Fig. 8, through the instrumentality of the spindle 23, the pinion 22 on the spindle, and the segmental gear 21 of the disk 13. This movement of the disk 13 in the direction of arrow (1 will place the last named disk in the position illustrated in Fig. 18, the bolts 20 being withdrawn from the body of the safe into the door, by the movement of the small pins 19 with which the bolts 20 are respectively provided, in the slots 18 of the disk, these slots being slightly out of line with arcs struck from the axial center or the door, this nonconformity being suiiicient to impart the necessary radial movement to the bolts 20 for locking and unlocking purposes. lVhen it is desired to lock the door, the position of the disk 13 will be reversed through the instrumentality of the spindle 23 and its connections, after which the rod 27 will be moved inwardly from the position shown in Fig. 14 to the position shown in 4. The pallet members may then be moved upwardly by the proper rotary movement of the spindle 74L and by virtue of the con struction and arrangement of parts heretofore described. Then, by imparting a partial rotary movement to one or more of the tumblers through the medium of the corresponding spindles 68 and their connections, the door will be locked and only person who knows the combination will be able to open it.
